#18244 of 18277 GM V8 Engine Oil Problem by drewmich Aug 08, 2009 (11:20 am)
My wife and I both have Buick Rainer -V8s - 2006 & 2007.   My wife's 2006 which has 50K mikes on it - is burning way too much oil - about a quart every 1500 miles. There are no leaks or drips on our garage floor and I don't see any blue smoke coming from the exhaust. We regularly get the oil changed every 6,000 miles   My 2007 Rainer (35,000 miles) - uses a bit less - a quart every 2000 miles.   Is there a known problem with these V8 GM engines used in the Rainers? Any possible warranty claims?   What solutions do any of you techs have to stop the oil usage? Replies to this message: snoking (Aug 14, 2009 9:37 am)

Replying to: pepito51 (Jul 25, 2009 6:11 pm) 79K seems a bit excessive for front brake pads; be sure someone competent looks at those front brakes.   Never changed your transmission fluid? Check it hot per the instructions in the owners manual. If it is brown or tinged brown, change the transmission fluid to add years and miles to the life of your transmission.   Change axle fluid per the owners manual recommendations. There really isn't any indicator otherwise except to keep the level up to spec. Replies to this message: pepito51 (Aug 13, 2009 3:10 am) cebteb (Aug 13, 2009 3:45 pm)
#18246 of 18277 Bilstein front shocks on Bravada worn? by cebteb Aug 12, 2009 (6:06 pm)
My 2003 Bravada has 42K miles on it and in the past few weeks the ride off he front suspension seems to have greatly deteriorated. The Bravada used to ride smoother than my wife's Chrysler 300M, but now when a front wheel hits a man-hole cover dip I get a big bang and jolt. Had an alignment and new tires done in spring. Air suspension on rear axle seems to still be very compliant.   Any thoughts on the sensibility of replacing the front Bilstein shocks that came stock with the Bravada and some of its sisters.

Replying to: cebteb (Aug 12, 2009 5:56 pm) Hey, cebteb.  I have all my servicing done at a major dealer, so I'm surprised they haven't tried to push brake pads on me yet. They always try to push something so they might this time. I'll ask them about it specifically. No one is better on brake life than me, however I have no teenagers or women drivers, so they last a lot longer even on other vehicles. I suspect when I ask the dealer, he'll want to replace them--kinda like asking the barber if you need a haircut Do they usually "turn rotors" on these vehicles as well?   Yes, I've changed the transmission fluid once (not the filter), at the dealer, using the "exchange" method at around 55,000. Next time I change it, I may have them do the the "drop pan" and new filter, etc. Is that what most people do, or do they continue using the exchange method over and over?   The dealer will probably try to push "fuel injector" treatment, but I run some powerful stuff through mine at intervals. Sometimes Techron, sometimes RedLine Engine Cleaner. Do people recommend the dealer fuel injector treatments? I have a Pontiac with 150,000 miles that has never had a dealer fuel treatment, just the ones I give it.   Thanks. Replies to this message: cebteb (Aug 13, 2009 3:45 pm)

Replying to: pepito51 (Aug 13, 2009 3:10 am) Rear pads can last 100K miles, but front pads go about half that. Ask them for a measurement of the front pad thickness; unless they lie or don't know how to measure the pad, that should give you the information you need regarding replacement. There seems to be a lot of opinions on this, but 1/16" seems to be the absolute minimum thickness (I think the wear indicators start to sing before this point, but I could be wrong), with most saying 3/32" or even 1/8" as the point at which they should be replaced.   Yes, they should turn the rotors when they change the pads. Since you have never had a brake job, the rotors should be okay to turn unless they are warped, in which case they require replacement for safe, quiet, and smooth future operation. Turning a warped rotor will often lead to a too thin remaining rotor, which will only warp again very quickly from heat during usage.   I think most folks just use the exchange method. When I changed mine at 39K (brownish ting to fluid), the dealer made no attempt to up-sell. In fact he really didn't want me to take the "pan drop" option as it was not necessary with the design of the system.   I've run some "powerful" stuff through my injector system, but my mileage has still deteriorated. I too would be interested in others comments on the dealer's injector cleaning service. I had an '85 Nissan 300ZX Turbo that required the multi-port injectors to be "rodded out" about every 40K miles else performance and mileage suffered badly. I don't know exactly what the dealers offer for these SUVs or whether it is at all worth it.
#18249 of 18277 P0442 error code on 2004 Rainier V8. by snoking Aug 14, 2009 (8:14 am)
Our Rainier is starting to repeatly get a P0442 error. Onstar twice said check the fuel cap for being tight. I reset the error with my code reader, but a couple months later I get it again. I checked the fill pipe seat and cleaned the gasket on the cap. Anyone else having this issue currently?   Chris Replies to this message: cebteb (Aug 14, 2009 10:01 am) glubash (Aug 14, 2009 3:53 pm) handyandy3 (Aug 15, 2009 5:56 am)
